This is a rare Mammites wingi fossil ammonite, dating back to the Turonian stage of the Late Cretaceous period (~93-89 million years ago), discovered in Penly Biville S Mer, France. Mammites belong to the Acanthoceratidae family, a group of ammonites known for their ornate, ribbed shells with distinct tubercles (nodes) and strong whorls. This 13-inch specimen is a stunning example of the species, showcasing well-preserved growth lines and intricate shell ornamentation.

The Turonian stage represents a period of rapid ammonite evolution, where species like Mammites wingi thrived in warm, shallow marine environments. Fossils from this time provide insight into the diversity of ammonite species before their eventual decline in the Late Cretaceous.

This exceptional specimen is a must-have for collectors, researchers, and fossil enthusiasts due to its impressive size, rarity, and scientific significance.
